Solution

The correct option is A

DNA replication takes place in S-phase


S-phase (synthesis phase) is the part of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase. Hence this is the correct statement.
The interphase generally takes between 18 and 20 hours. Mitosis, the process during which the cell makes preparations for and completes cell division, only takes about 2 hours.
G2 phase, or Gap 2 phase, is the second subphase of Interphase in the cell cycle directly preceding mitosis. It follows the successful completion of S phase, during which the cell's DNA is replicated.
G1 phase is the part of interphase, where the cell synthesises mRNA and proteins in preparation for subsequent steps leading to mitosis. S-phase (synthesis phase) is the part of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase.
